The Stay Awake sounded particularly sinister Saturday night at O’Leaver’s. Frontman/guitarist Steve Micek explained from stage that he couldn’t “feel” with his ring and pinkie fingers of his left hand after having pinched a nerve. “I’m getting old,” he said. Aren’t we all? Regardless, no one in the audience could tell he was suffering from this temporary disability. The band sounded as raw and unnerving as it always does. They don’t make it easy on their audiences, nor do they try to. The trio’s music is rhythmically violent — a throbbing math equation that solves itself by kicking over the instructor’s desk and kneeing him/her in the groin before scrawling a giant “Fuck You” on the chalk board with the skin/blood of their fists. I like this band; I like them even more when they “lock in” and drive everyone right over the edge with no intention of slowing down. Circumstances have placed The Stay Awake’s future in question. I strongly suggest you catch them the next time they play, because it may be your last chance.

Saturday night also was the debut of Millions of Boys, a new band by Honey & Darling bassist/guitarist/vocalist Sara Bertuldo. She’s primarily playing guitar in this new trio that sounds more cuddlecore K Records poppy than her other band, which also played Saturday night. It’s the first time I’ve seen Honey & Darling in about six months, and they’ve honed their sound to a glistening edge, no matter what instrument any of the members end up playing on any given song (They change it up a lot). In both bands, Bertuldo’s soft, sweet voice could barely be heard over rhythm sections. Frankly, there’s not much a club like O’Leaver’s — with its limited PA — can do about someone who sings just barely above a whisper when the rest of the band is in flames.
